Spoiler alert: The band appeared as wildling warriors in last night's episode "Hardhome," in which Lord Commander of the Night's Watch Jon Snow tried to rally some wildlings to prepare for the oncoming battle with the White Walkers, only to have the undead come knock down their walls and decimate nearly everyone in sight, turning them into even more undead warriors. As far as TV sequences go, it doesn't get more metal.

Here's what the band's Brann Dailor (which is a pretty "Thrones"-ish name) had to say about it, as reported by Stereogum:

"It was such an incredible experience to be on set as extras for our collective favorite show Game Of Thrones and to be wildlings murdered and then brought back to life by White Walkers was beyond amazing. I watched my best friends Brent and Bill, murdered right in front of me as I myself was stabbed in the stomach and had my throat slit multiple times, and I didn’t mind at all. It made me love being in Mastodon even more. We are more than privileged and honored to have been a part of one of the greatest stories ever told on film, and the catering wasn’t bad either."

Mastodon previously submitted the song "White Walker" for the Catch the Throne Vol. 2 mixtape earlier this year.

Showtime's critically acclaimed "Masters of Sex" follows Dr. William Masters (Michael Sheen) and Virginia Johnson (Lizzy Caplan) as they research human sexuality at Washington University in St. Louis, Missouri in the late 1950s and early '60s. It is based on Thomas Maier's biography Masters of Sex: The Life and Times of William Masters and Virginia Johnson, the Couple Who Taught America How to Love.

“Game of Thrones” ended its fourth season in its own spectacular fashion of killing off as many characters as possible in an hour-long show. The finale “The Children” wrapped up a number of this season’s storylines, which I’ll review below.

The episode started with picking up off of last week’s exciting battle at the wall, with Jon Snow heading off to face (and possibly kill) Mance Rayder, the leader of the wildlings. If you’ll recall, the wildlings got some help to bolster their numbers from the cannibal Thenns in episode one. Jon Snow had returned from the wildlings, saying he traveled with them to gather information. Snow and others thwarted a group of mutineers at Craster’s Keep, saving his own brother, Bran, and his crew in the process without even knowing it (a diversion from the books, I’m told). Master-at-arms of the Night’s Watch Alisser Thorne grew weary of Snow’s increasing leadership or impetuousness, depending on how you look at it, but Snow proved to be right about sealing the tunnel beneath the wall, which was breached by a giant during the wildlings invasion of the wall, during which Snow’s ex-lover and wildling Ygritte was killed. In the finale, Snow believes killing Rayder will split up the wildlings, but he is somewhat disarmed by Rayder’s decidedly unbarbaric nature.

Even with last week’s thrilling fight that ended in the deaths of two characters and the fate of Tyrion Lannister looking grim, last night’s episode of “Game of Thrones” might have been the most exciting yet. Dramatically though, it’s a different story.

The episode began with Jon Snow and Samwell Tarly talking about love like it’s a damn Lifetime movie, not a TV show where people are regularly bludgeoned to death onscreen. Cheesy as it might have been, we knew it was just the calm before the storm. And what a storm it was—basically a Gallagher concert’s worth of blood sprayed onto viewers for about 45 minutes, with the occasional flick of storytelling thrown in the mix. Look! There’s Gilly, miraculously finding her way to Castle Black. Hey! Janos Slynt is kind of a wuss, hiding from the battle in the food cellar with her. And we were all waiting to see what happened with Ygritte and Jon Snow. But mostly it was just one big bloody battle.

On one hand, the battle was a spectacle to behold. And for a fantasy show set in a place beset by constant battle, the show is surprisingly light on actual fighting (aside from, you know, major characters dying in terrible ways all the time). Barring the battle of the Blackwater in season two, this was the mother of all fights in the show on an episode that smartly eschewed the regular multitiered storytelling to keep us held in the grips of the battle. Truly stunning were the wildling giants riding on mastodons, terrifying and even seemingly realistic.

Last night’s episode of “Game of Thrones” contained yet another major character’s death, which has especially been a trademark of this season of the show.

After Oberyn Martell aka The Viper revealed a long-held vendetta against The Mountain and all of the Lannisters for the rape and murder of his sister and her children, the cards seemed to be stacked against the ginormous Mountain. After all, what could a mountain of a man do against a deadly warrior with years of built up resentment do?

A lot, it turns out. The battle between The Viper and The Mountain was the most exciting fight sequence yet on “Game of Thrones,” pitting The Viper’s acrobatic skills against The Mountain’s brute strength, with many of the show’s major characters looking on, awaiting Tyrion Lannister’s fate via trial by battle. And The Viper did get the upper hand, mortally wounding The Mountain several times.

But true to its mythical, nearly Biblical allusions—“The Viper and The Mountain” sounds at least like a fable if not something out of the Old Testament—pride was the ultimate winner of this fight. Drunk and blinded by hatred, The Viper resisted finishing off The Mountain until he said Elia Martell’s name, the woman he raped and murdered. The Mountain finally obliged—while bludgeoning The Viper’s face until his brains exploded out of his skull, before dying himself. Not only was this the most exciting fight ever in GoT, it was also the most bloody disgusting.
